Title: Improvements in bed tables, book rests and the like
IPC: A47B23/02
Filed: 1933-05-25
Abstract: 414,869. Desks. PAYNE, L. W. G., and CARTERS, Ltd., J. & A., 2, New Cavendish Street, London. May 25, 1933, No. 15185. [Class 52 (iii).] A bed table, book rest, or like article is made with a slot into which is fitted a strip held frictionally in any position of adjustment. The Figure shows a resilient metal strip 1 fitted in a slot 4 ; it has a slight curvature, so that it presses the sides of the slot, and is held frictionally. It is slotted to move on screws 5. A non-resilient strip may be similarly held by spring-pressed balls or washers, or flat springs. If the strip 1 is of wood, and is thick enough, the springs or washers may be let into recesses in them.

Title: Improvements in the preparation of Nuclear Reactor Fuel materials
Inventor: HALVA CARROLL JOE
IPC: G21C3/62
Filed: 1967-04-03
Abstract: 1,187,243. Nuclear fuel. BABCOCK & WILCOX CO. 3 April, 1967 [1 April, 1966(2)], No. 15212/67. Heading G6C. [Also in Division C1] Nuclear fuel particles containing fertile and fissile material in oxide form are made by treating gel particles containing fertile material with a liquid containing the fissile material and calcining the resulting gel particles, which may have a fissile content of up to 15 atom per cent. For example thoria sol is dried by evaporation or is converted to spheroids by passing droplets through a dehydrating solvent, the gel particles formed being graded according to size; the particles are contacted with aqueous uranyl nitrate solution (containing U235) by stirring together, by passing the solution over a column of the gel particles, or, preferably, by allowing the particles to fall freely through the treating solution and then into a body of wash and dehydrating liquid, for example a mixture of acetone with carbon tetrachloride or trichlorethylene. The gel particles are calcined at above 1100‹ C. in an argon-hydrogen atmosphere, placed in a tubular container and compacted to high density by vibration or swaying to form a fuel element. Uranyl fluoride, acetate, chloride, or sulphate may be used in the treating liquid instead of uranyl nitrate. Fuels comprising U238 as the fertile material and U233, U235, or Pu as the fissile material may be made by similar processes.

Filed: 1974-04-05
Abstract: 1471058 Air cushion device for supporting and anchoring KOEHRING CO 5 April 1974 [6 Aug 1973] 15265/74 Heading B7K [Also in Division F2] A movable platform for vibration testing of a vehicle comprises a base which, in use, rests on a floor surface, means secured to the base for supporting at least part of a vehicle, vibrating means connected to the support means, and air pressure control means selectively operable to either direct pressurized air between the base and the floor surface to facilitate movement of the platform over the floor surface or to evacuate air from between the base and the floor surface in order to vacuum lock the platform. In the embodiment described, the platform supports a vehicle wheel and simulates vibration in the vehicle, such as might occur during driving. It includes an hydraulic actuator 12 for vibrating a load-receiving tray 14, shown supporting a vehicle wheel 22, the actuator 12 being supported on a platform base 16. The hydraulic drive 18 for the actuator 12 is also supported on the base 16. Actuator 12 comprises an hydraulic piston 26 reciprocable within a cylinder 24 secured at its lower end via a mounting block 36 to the base 16. The base 16 includes an upper plate 52 having a central opening 54 and a lower plate 60 having a plurality of openings 62 spaced over its entire area. These openings 62 are of reduced diameter at their lower ends. The plates 52, 60 are secured together by bolts 68 and held in spaced apart relation by washers 70 to provide an intermediate manifold chamber 72. A gasket 74 positioned around the periphery of lower plate 60 is secured in position by means of a clamp 76 secured to upper plate 52 by bolts (not shown). The gasket 74 and clamp 76, together with an additional gasket 84, provide a peripheral seal for the manifold chamber 72. Air under regulated pressure can be supplied to the chamber 72 from means 86 via one branch of a T-connector 88 and the opening 54, by turning the valve handle 92. The air pressure will attempt to dissipate through the openings 62 in the bottom plate 60 and will provide an air bearing beneath the base 16 to facilitate movement of the load support platform. When it is desired to secure the platform in any desired position on a smooth floor 94, the air pressure is turned off and a vacuum drawn in the chamber 72 by means 90 via the other branch of the T-connector 88 and the opening 54, by turning the valve handle 96. The gaskets 74, 84 provide an initial seal around the periphery of base 16 and as the vacuum is drawn, the seal is increased. Considerable holding pressure may thus be provided on the base 16 without marring the floor 94.

The dyes are prepared by reacting together 1 mol. of the diazo compound of a suitably substituted 2-aminophenol, 1 mol. of a coupling component of formula <FORM:0955313/C3/2> wherein y is an exchangeable hydrogen atom and 1 mol. of a reactive component, i.e. a polyhalopyrimidine or a functional derivative of a halogenoalkanoic acid with 2 or 3 carbon atoms, the reaction being conducted so that the diazo compound couples ortho to the hydroxy group and the reactive component replaces y; the treatment with a copper- or nickel-yielding agent taking place after the coupling and the reaction with the reactive component before or after coupling or after metallization.  The dyes may be used to colour wool, silk, leather, synthetic polyamide fibres and cellulose fibres in red-violet to blue-violet shades.  The dyeing may be followed by an alkaline after-treatment. Examples describe the preparation of the dyestuffs and their use in dyeing cellulose fibres.

[Class 35] [Also in Group XL] An apparatus for discharging electricity from materials or machinery comprises a casing 33 having an air inlet 38 and an outlet 37 with means, e.g. an electrically driven fan 40, for causing a stream of air to flow through the casing and containing a spark gap 41a having zinc or cadmium electrodes 41 for ionizing the air included in an electric circuit through which flows a high-frequency high-potential alternating current. The casing, which is portable, contains a transformer or induction coil 34, the secondary winding of which is shunted by a low-value capacity 42 of about À002 microfarad and connected to the electrodes in series with a low-value inductance, e.g. a single turn of copper tape 43. A grid 49 within the outlet may be biassed so that only positively or negatively charged particles can emerge, and the biassing potential may be derived from a rectifier fed from an auxiliary secondary winding on the transformer. In a modification, for de - electrifying photographic apparatus mounted on an aircraft, the camera is contained in a casing through which air from the ionizing apparatus is conducted. The air flow is obtained by the use of a funnel open in the direction of travel of the aircraft or the funnel may be replaced by a pump or fan driven by a wind motor ; alternatively, the pump may be arranged at the outlet of the camera housing to draw air through the system. The air pipes are preferably coiled to act as light baffles and the air entering the casing 33 may be filtered.
